BATTLE CREEK, MI -- A fire that forced the evacuation of a Battle Creek senior citizen apartment complex is under investigation.

Firefighters were dispatched to the fire at Lakeview Meadows at about 8:30 p.m. Monday, according to a news release. When they arrived, smoke and fire could be seen coming from the building, which was still occupied.

Officers from the Battle Creek Police Department immediately began moving occupants out of the building. Some of the elderly residents needed to be carried down stairs from the second story, police say.

As the officers were evacuating the building, firefighters learned that a section of the building's roof had collapsed. Officers were able to clear the entire east building that was still on fire without any injuries, according to the news release.

The Lakeview Meadows west building was also cleared as a precaution. Lifecare Ambulance, Lakeview Baptist Church and The Red Cross assisted with helping displaced residents find family members and temporary shelter.
